Pup is different from IR with possible return. You can have lots of PUP but they cannot have practiced in training camp. So Savion cannot be on pup, but Williams, Oliver and Watson can. For IR with no return, I think they are unlimited. I think glover goes there, not sure if any others will be red shirted. IR with return I think is limited to 6 per season. Thinking maybe sorrel and/or Savion. I do not think any of these count against the 53.
